Ad 1)
There are many environmental problems in the world today:
• global warming
• the holes in the ozone layer
• the greenhouse effect
• acid rain
• cutting down and burning tropical rainforests
• air pollution, water pollution, soil pollution.
Global warming is caused by the greenhouse effect. The heat from the sun is trapped in the atmosphere. The earth is getting warmer. The temperature rises. The snow at the poles begins to melt. Sea levels start to rise. There are floods and droughts. The weather is very changeable and often unpredictable.
There are holes in the ozone layer. They are caused by chemicals called freons. The ozone layer protects the people and the earth from the sun´s ultraviolet radiation. Ultraviolet radiation may cause skin cancer.
The earth suffers from acid rain. Raindrops contain poisons from the gases that are produced by burning fossil fuels (oil, coal, natural gas). Acid rain damages plants, trees, fish in lakes and rivers and buildings.
Tropical rainforests are important for the health of earth. Many species of plants and animals live there. These rainforests are cut down for wood or burned to clear the land for farming.
